About this study

Official title: Assessing Catabolic Marker Levels in the Knee Synovial Fluid Microenvironment After Lavage With Platelet Poor Plasma (PPP)

The purpose of this study is to understand how the components of osteoarthritic knee joint fluid (synovial fluid) change after lavage treatment with platelet poor plasma. Additionally, the study participants will complete outcome questionnaire surveys before and after the treatment in conjunction with when synovial fluid is removed from the knee (2, 4, and 6 weeks after lavage). This data will help determine if the treatment of an osteoarthritic knee joint with platelet poor plasma lavage is a suitable stand-alone therapy or to improve outcome by preparing a patient's knee for further regenerative therapies.

Read the detailed description

The objective of this study is to quantify the levels of catabolic markers in osteoarthritic (OA) knee synovial fluid microenvironment (ME) before lavage treatment with platelet poor plasma (PPP) and to determine whether the anti-catabolic capabilities of the PPP are sustainable or if the diseased synovial fluid returns to pre-lavage catabolic marker levels within the 6 week period of the study.

This data will be used to determine if treatment of a diseased (OA) knee with PPP lavage would be a suitable therapy for knee OA patients either as a stand-alone treatment or to improve outcome by preparing a patient's knee microenvironment for further treatment with cellular therapies. Incidence of post-operative complications, adverse events, re-injections, and surgical intervention; change in pain score will be considered while determining these direct and indirect associations upon completion of the PPP lavage treatment. Correlation of subject reported clinical outcomes for the PPP lavage treatment will be evaluated to determine whether the treatment provides beneficial clinical outcomes.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Lavage with Platelet Poor Plasma (PPP)Biological

    Lavage of 50cc PPP

Study groups in NCT03120988
Study groupRoleWhat they receive
Lavage with Platelet Poor Plasma (PPP)ExperimentalLavage using 50 cc of PPP in the knee joint. Using visual guidance, the PPP lavage will be conducted, introducing a solution of platelet poor plasma into the knee joint with subsequent removal of the fluid, in effect "washing out" the joint space.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Lavage with Platelet Poor Plasma (PPP) in people with Knee Osteoarthritis, run by Regenexx, LLC at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mean temporal biomarkers (pg/ml) (time frame: 4 weeks post treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03120988, which also lists 9 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Jul 2019.
